Biocalcite, a multifunctional inorganic polymer: Building block for calcareous sponge spicules and bioseed for the synthesis of calcium phosphate-based bone
Beilstein J. Nanotechnol. 2014, 5, 610–621, doi:10.3762/bjnano.5.72
- is the material that builds up the spicules of the calcareous sponges. Recent results revealed that the calcium carbonate/biocalcite-based spicular skeleton of these animals is formed through an enzymatic mechanism, such as the skeleton of the siliceous sponges, evolutionarily the oldest animals that
- suitable matrix to embed bone forming cells for rapid prototyping bioprinting/3D cell printing applications. Keywords: biocalcite; bioprinting; bone; bone formation; calcareous spicules; sponge; Introduction The size and complexity of a metazoan taxon is correlated with the dimensioning of its respective
Nano-FTIR chemical mapping of minerals in biological materials
Beilstein J. Nanotechnol. 2012, 3, 312–323, doi:10.3762/bjnano.3.35
- observe a reproducible vibrational (phonon) resonance within all biocalcite microcrystals, and distinctly different spectra on bioaragonite. Surprisingly, we discover sparse, previously unknown, 20 nm thin nanoparticles with distinctly different spectra that are characteristic of crystalline phosphate
- -forming organism We demonstrate nano-FTIR near-field microscopy on a Mytilus edulis (M. edulis) shell specimen, which exhibits easily resolvable fibrous biocalcite microcrystals and tablet-shaped bioaragonite nanocrystals. On a polished section, the expected characteristic interface [33] between an outer
- 10 × 10 µm2 area each were consecutively acquired and stitched together. The topography (Figure 2a) exhibits the arrangement of (i) fiber-shaped biocalcite crystals with slightly oblique, flat surfaces at a few distinctly different heights, (ii) deep depressions mainly in the interlayer, and (iii
